All Hardware and Installation Instructions Included!
Whatever your task at hand -- whether it's launching that boat before daybreak, setting up your camper before the rush or getting a final load to the dump before close -- CURT class 3 trailer hitches offer the strength needed for serious towing. They make it easy to hitch up and Bring It, offering a vehicle-specific fit and the weight capacity to handle a variety of trailers. Custom class 3 hitches are the most common type of receiver hitch for pickup trucks and SUVs. Because of their weight range, they are also found on full-size cars, crossovers and minivans. Each custom-fit class 3 hitch package is made for vehicle-specific mounting. This particular kit fits certain years of the Hyundai Tucson and Kia Sportage (see application info to verify vehicle compatibility). It provides a weight carrying capacity of 3,500 lbs. GTW and 350 lbs. TW. CURT class 3 trailer hitches are typically used to attach and haul utility trailers, boat trailers, campers, snowmobile or ATV haulers and more (NOTE: Never exceed the lowest-rated towing component). Each class 3 hitch has a 2" receiver tube and is tested in accordance with SAE J684 for safety. To ensure that CURT class 3 receiver hitches have what it takes for serious trailering, they are designed using a hands-on approach and are constructed with rugged, high-strength steel and precise welding. We also protect our class 3 hitches in a co-cured finish of liquid A-coat and black powder coat for superior resistance to rust, chipping and UV damage.
CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Although this special socket is not equipped on every vehicle, a CURT custom wiring connector -- also called a T-connector -- utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard, universal vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular plug-in connector provides a 4-way flat socket and is designed to be a custom wiring option for certain years of the Kia Sportage (to verify your vehicle compatibility, see application info). It comes with all necessary hardware to establish a solid connection. It also comes with a dust cover to keep the connector socket clean when not in use. To ensure long-lasting reliability, all CURT custom wiring connectors are thoroughly tested for optimal functionality. Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it.

No. The installation instructions require you to remove the tow hooks before installing the hitch. The manual states 'Remove tow hooks and return to customer' as step 2 of the installation process. The manual does not specify whether this removal is permanent or whether the hooks can be reinstalled after the hitch is mounted.
The gross load capacity when used as a weight-carrying hitch is 3,500 lbs trailer weight and 350 lbs tongue weight. However, you must not exceed your vehicle manufacturer's recommended towing capacity, which may be lower.
The hitch weight is 60 lbs.
The kit includes 6 hex head cap screws (HHCS) M10×1.25×35 mm, grade 10.9, zinc-plated (part 10-10298) and 6 conical washers (part 30-00163). These fasteners secure the hitch to the existing frame weld nuts.
No. The manual explicitly states 'NO DRILLING REQUIRED'. The hitch uses existing frame weld nuts on both the driver and passenger side frame rails.
Yes. Step 1 of the installation instructions requires you to 'Remove exhaust hangers and lower exhaust for ease of installation.' Step 5 requires you to reinstall the exhaust hangers after the hitch is secured. The manual does not provide detailed instructions for exhaust removal or lowering.
All 10 mm fasteners must be torqued to 48 lb-ft.
1. Remove exhaust hangers and lower exhaust. 2. Remove tow hooks and return to customer. 3. Raise hitch into position and secure with hex bolts and conical washers through existing weld nuts in frame rails. 4. Torque all 10 mm fasteners to 48 lb-ft. 5. Reinstall exhaust hangers.
The hex bolts and conical washers pass through existing weld nuts located on both the driver side and passenger side frame rails. The hitch is raised into position and secured using these existing frame attachment points.
Periodically check the receiver hitch to ensure that all fasteners are tight and that all structural components are sound. The manual does not specify the interval for these checks or provide a detailed inspection procedure.
No. The manual states: 'DO NOT EXCEED VEHICLE MANUFACTURER'S RECOMMENDED TOWING CAPACITY.' Even though the hitch is rated for 3,500 lbs trailer weight and 350 lbs tongue weight, you must follow your vehicle manufacturer's lower towing limit if one exists.
Alteration to, misuse of, or improper installation of the hitch voids the warranty. Curt Manufacturing's liability is limited to repair or replacement of defective products and excludes liability for incidental or consequential loss or damage.
The Curt 55529 is designed for Kia Sportage V6 models only. If your Sportage has a V6 engine, this connector will fit. If you have a different engine type, this product is not compatible. Check your vehicle's owner's manual or contact the vehicle manufacturer to confirm your engine type.
The Curt 55529 has two amperage ratings: Signal Circuits are rated at 3.0 amps per side, and Tail/Running Circuits are rated at 6.0 amps total. Do not exceed these ratings or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire.
The manual does not specify required tools. However, based on the installation steps, you may need a drill with a 3/32" bit (if drilling a pilot hole for the ground screw), a screwdriver, and possibly a wrench or socket to secure the ground screw with its nut. Contact Curt Manufacturing for a complete tool list.
The vehicle connector is located on the passenger side of your Kia Sportage, between the bumper and rear tire. The connector is marked as S5 and is positioned behind the driver side rear bumper. You will need to remove a protective cover to access it.
Locate the vehicle connector on the passenger side between the bumper and rear tire. Remove the protective cover carefully, taking care not to damage the locking tabs. Insert the custom wiring harness into the vehicle connector, ensuring the connectors are fully inserted and the locking tabs are in place. The connectors must be fully seated for proper function.
Locate a suitable grounding point near the connector, such as an existing screw with nut in the vehicle frame. If no suitable point exists, drill a 3/32" pilot hole for the provided screw. The area must be free of rust, dirt and paint. Secure the white ground wire using the ring terminal and provided screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Locate a flat spot inside the vehicle near the taillight and adhere the black converter box using the provided double-sided tape. The box should be mounted in a secure, accessible location.
When in use, route the 4-flat to the center of the vehicle and out of the trunk. When not in use, roll up and store in a convenient, out-of-the-way location inside the trunk. Secure any loose wires with the provided cable ties to prevent tangling and damage.
After installation, reinstall all items removed during the install. Install the provided 4-flat dust cover to help prevent corrosion. Test the connector for proper function by using a test light or connecting a properly wired trailer. All steps must be followed to ensure the wiring connector will function properly.
Drilling may be required. If a suitable grounding point (such as an existing screw with nut in the vehicle frame) is available near the connector, you can use that. If not, you will need to drill a 3/32" pilot hole for the provided ground screw. Before drilling, check for hidden items behind or under any surface to avoid damage and personal injury.
Do not exceed the product rating (Signal Circuits 3.0 amps per side, Tail/Running Circuits 6.0 amps total) or your tow vehicle's lamp load rating, whichever is lower. Exceeding the product rating can cause loss of warranty, overheating and potential fire. Additionally, check for hidden items before drilling to avoid damage and personal injury.
Test the connector for proper function by using a test light or connecting a properly wired trailer. All installation steps must be followed to ensure the wiring connector will function properly before testing.
Yes, if your Sportage has a V6 engine. The Curt 55529 is designed for Kia Sportage V6 models only.
Signal Circuits: 3.0 amps per side. Tail/Running Circuits: 6.0 amps total. Do not exceed these ratings or your vehicle's lamp load rating, whichever is lower.
Possibly. If an existing screw with nut is available in the vehicle frame near the connector, no drilling is needed. Otherwise, you will drill a 3/32" pilot hole for the provided ground screw.
